C# http post 中文亂碼問題

request.ContentType = "application/json; charset=utf-8";

 

這種的postdata 在寫入 Stream的時候要確保編碼是  utf-8

 

                string postData = "中文亂碼問題";
                UTF8Encoding encoding = new UTF8Encoding();
                byte[] bytepostData = encoding.GetBytes(postData);
                request.ContentLength = bytepostData.Length;
                //發送數據 using結束代碼段釋放
                using (Stream requestStm = request.GetRequestStream())
                {
                    requestStm.Write(bytepostData, 0, bytepostData.Length);
                }
